He was clearly reading this for a really good story.A totally normal manga. Nothing to see here, folks, move along.
Please go to churchImagine if Kouhei had been gooning and had the blanket over his legs AND THEN SUDDENLY KAEDE JUST JUMPS ONTO HIS BED. And him saying "Ah.. well.. i've been waiting for you to do it.." IN THAT SITUATION?? Without context it seems like he's saying that "doing it" is a "Childhood Friend Experience"! also i know there are extras with Kaede cosplaying like Santa claus so maybe we can get a bunny girl Kaede?
